Engineer's Note

Compared with the previous-generation MZWLR3T8HALA, the Samsung PM1733A MZWLR3T8HCLS moves to a newer 6th-Gen 128-layer V-NAND platform and fully exploits PCIe Gen4 x4 bandwidth, delivering up to 7,000/3,800 MB/s and 1,450,000 random-read IOPS for substantially higher host-side throughput and faster response under parallel workloads. With 3.84 TB capacity, 1 DWPD, and 7008 TBW, it provides a stronger endurance-to-performance balance than its predecessor, making it a particularly solid fit for virtualized databases, read-intensive analytics, and mixed enterprise application tiers.

Endurance & Reliability

With an endurance rating of 7008 TBW and 1 DWPD, this SSD is designed to handle writing its full capacity once per day across a standard enterprise service life, which is far beyond the needs of typical boot, OS, and general application workloads. In practical purchasing terms, that means it can be deployed as a system drive or mixed-use enterprise SSD with strong long-term write durability, and in lighter real-world usage it can operate for many years with substantial endurance headroom. Its enterprise-grade reliability is further strengthened by power loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption or incomplete writes. Combined with an ultra-low UBER of 1.0E-17 and a 2 million-hour MTBF rating, it is built to deliver very high data integrity and dependable operation in business-critical environments.

Technical Specs & Insights

1. The PCIe Gen4 x4 interface provides a high-bandwidth host path that removes storage bottlenecks in virtualized infrastructure, analytics clusters, and latency-sensitive enterprise applications.
2. With sequential read performance of 7000 MB/s, this SSD accelerates large-file movement, database backup windows, and dataset streaming for AI and HPC workloads.
3. Delivering 1,450,000 K IOPS in random reads, it is well suited for metadata-heavy databases, high-concurrency VM farms, and read-intensive OLTP environments that demand fast small-block access at scale.
4. Rated at 1 DWPD, the drive can sustain predictable full-drive rewrites every day throughout its service life, making it a strong fit for mixed-use enterprise deployments that need balanced endurance and TCO.
5. Built on Samsung V-NAND 6th-Gen 128-layer 3D TLC and paired with a typical latency of 85 µs, it combines dense flash efficiency with consistently fast response times for transactional workloads and tier-1 server storage.

Capacity Sweet

Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB The 3.84 TB model sits at the sweet spot of this SSD family. Compared with the 1.92 TB version, it gives much better capacity headroom for growth, reducing early drive exhaustion and improving planning flexibility for mixed enterprise workloads. Compared with the 7.68 TB option, it typically delivers a better balance of acquisition cost, usable capacity, and the same class of enterprise read/write and random IOPS performance. It is especially well suited for mid-scale virtualization clusters, database nodes, or all-flash storage pools serving roughly 40-60 business applications.
